1449291-16-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1449291-16-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,2,9 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1449291-16:
(9*1)+(8*4)+(7*4)+(6*9)+(5*2)+(4*9)+(3*1)+(2*1)+(1*6)=180
180 % 10 = 0
So 1449291-16-0 is a valid CAS Registry Number.
